A new kind of novel control method which is named backstepping synchronous control is firstly proposed in this paper. It is a kind of method that can applied in any general system as widely as PID control, variable structure control and any other control method. Synchronization was most frequently used in secure communication and else in the past, but here its concept was successfully used to construct a new control method. It is similar to model referenced adaptive control but it is still different from that. An auxiliary system with several virtual synchronous inputs and a real input is constructed to cope the uncertainties of original system. The synchronous inputs are designed to realize the synchronization between auxiliary system and original system. Since the real input is designed according to the auxiliary system without uncertainty by using backstepping method, so it is easy to design. Because the synchronous input is decoupling so it is easy to cope with uncertainties. In this paper, simplified supersonic missile system was taken as an example to show the design process and stability analysis of the new method. Also, it was compared with traditional PID control and backstepping control method. At last, detailed numerical simulations were done to testify the effectiveness of the proposed method.
